Today in the greenhouse, I noticed hundreds of little black flowers all over my almost head-high Pittosporum 'Garnettii'. How could I have missed them? That must be what is scenting the big volume of air in my greenhouse, not the four little muscari flowers. I have the muscari on the kitchen table, and it now has a sweet scent when I sniff its flowers. I guess it hadn't developed its scent two days ago when I first checked it. Thank you, everyone, for your help. Diane Whitehead
